I wouldn't focus on negative answers...
It's ALL POSSIBLE!
Yes it is sustainable... At least for one person as well as you are doing already, dealing with unconscious waste.
MAYBE it will be sustainable for an entire family, moreover if you are all CONSCIOUS human beings and focus on some CURRENT tendencies in that direction around the world (YES, you're not alone!):
- Food:
- Shelter / Home:
- Productivity from waste:
Not about waste transformation, but related:
- Hard Money (Non-Fiat currencies)
- Sovereign Citizens or Freemen (living under own laws no matter the country, obviously this doesn't allows you to surpass others laws, there's many movements in many countries, but it's a legal complication in many matters)
As you can see, there's many of this anti-waste tendencies, some being really applied in Germany and France (very conscious countries on waste-transforming which is usually called RECYCLING, which in this continent's society is on pampers). Maybe you could make some research on those countries and their tendencies to find much more useful things.
I'm doing my thing too, and you know what? some of the richest persons I've known have made their way from ground-up through this kind of waste-transforming-tendencies that aren't adopted by the mayority of us (recycling, green bonds, biogas, etc), done massively, but yes, little by little.
For whom this all is MORE sustainable is for the entire world, humanity and mother earth, so I want to give you a BIG THANK YOU! in name of us all, you are a living example and you should SHARE IT.
Internet is information, and information is... POWER!
With enough information you have the power to transform EVERYTHING!
Nothing is created, nor destructed, only transformed. (Laws of Thermodynamics, Conservation of energy and Conservation of mass).
